A feedback system is a systems that "controls, regulates and coordinates a specific cell functionality"
Feedback loops imply a before and after condition
which make feedback a "dynamic system"
A genetic regulatory network (GRN) is an an example of a feedback system
A GRN
is a collection of DNA segments in a cell which interact with each other and with other substances in the cell, thereby governing the rates at which genes in the network are transcribed into mRNA.
SYSTEMS BIOLOGY is the area of study

A feedback system can be any system which uses the output of the system to provide direction/regulation to the activity of the system. For instance the level of hormones in the body that are produced by a particular gland will literally go back to that gland and indicate to the gland how much more or less may need to be produced. A real life example of this feedback is what happens when men use anabolic steroids. These injected steroids go back/feedback to the man's testicles telling them that the level is fine/high so don't produce any. After time the testicle begins to shrink/atrophy, much like a muscle will, due to lack of use since the body is getting hormones artifically.
